As with anything which modifies your disk's contents, this program can cause SIGNIFICANT data loss, and you are advised to make sure your data is backed up before beginning the installation process.
Default answers are displayed in brackets after the questions. You can hit Control-C at any time to quit, but if you do so at a prompt, you may have to hit return. Also, quitting in the middle of installation may leave your system in an inconsistent state.

OK, then. Enter `halt' at the prompt to halt the machine. Once the machine has halted, power-cycle the system to load new boot code.
Note: If you wish to have another try. Just type '^D' at the prompt. After a moment, the installer will restart itself.

CONGRATULATIONS! You have successfully $what NetBSD! To boot the installed system, enter halt at the command prompt. Once the system has halted, reset the machine and boot from the disk.
Note: If you wish to have another try. Just type '^D' at the prompt. After a moment, the installer will restart itself.
